How UK Mortgages Work
UK mortgages differ from US mortgages in several key ways:
Loan-to-Value (LTV)
The percentage of property value you're borrowing. Lower LTV means better interest rates.
Stamp Duty
UK property tax paid on purchase. Tiered rates from 0% to 12% based on property value.
Mortgage Terms
Typically 25 years in the UK, though 15-35 year terms are available.
Deposit Requirements
Usually 5-20% of property price. Higher deposits secure better rates.
Key UK Mortgage Concepts

England & Northern Ireland rates: 0% up to £250k, 5% on £250k-£925k, 10% on £925k-£1.5m, 12% above £1.5m. First-time buyers pay 0% up to £425k.
LTV Ratios
95% LTV = 5% deposit, 80% LTV = 20% deposit. Lower LTV typically means interest rates 0.5-1% lower.
Fixed vs Variable Rates
Fixed rates lock in for 2-5 years. Variable rates follow Bank of England base rate changes.
